" ED .STATEfi 4 Claims. l

The'present invention relates to collar fasteners and has for its mainobject the provision of a fastener for engaging collar wings, with meanstherein provided for prompt disengagement.

A still further object of the present invention is the provision in afastener of the type above indicated of means for automatic engagementof collar wings when inserted into the fastener, with means for promptdisengagement thereof.

A still further object of the present invention is the provision of afastener having opposed pins piercing collar wings when inserted intothe fastener, with means cooperating with said pins for shifting thesame angularly of the body of the fastener and thereby promptlydisengaging the same from the collar.

A still further object of the present invention is the provision of afastener having a pair of spaced bars with disengageable meanstherebetween for engaging fabric material.

With the above general objects in view and others that will appear asthe invention is better understood, the same consists in the novelconstruction. combination and arrangements of parts hereinafter morefully described, illustrated in the accompanying drawing and pointed outin the appended claims.

In the drawing forming a part of this application, and in which likedesignating characters refer to corresponding parts throughout theseveral views;

Fig. 1 is a top plan view of the invention;

Fig. 2 is a side elevational view thereof;

Fig; 3 is a bottom elevational view thereof Fig. 4 is a side elevationalview of pin constituting part of the present invention and intended forengagement with a collar wing; and

Fig. 5 is a cross-sectional View on line 5-5 of Fig. 2.

Referring in detail to the present drawing the fastener includes a frontarcuate bar lb, pro vided at each of its free ends with decorativeenlargement ll.

Cooperating with said front bar it is rear bar 52, which issubstantially on the same plane with bar l8, and is rigidly lockedthereto and centrally thereof by means of a pair of opposed tongues l3,which are bent around said rear bar 5?. as is clearly seen in Fig. 3.

Said rear bar i2 is slightly longer than said front bar Ill.

Said bar 12 laterally of said tongues i3 is bent away from front barill, effecting bulges 14 for providing spaces there between and saidfront bar it wherein the vertical hems of collar wings are accommodated.

Past said bulges 54 said rear bar i2 is bent towards said front bar it,effecting elevations l5,

5 facing the adjacent ends of front bar it and substantially opposite.of said enlargements ll.

Each end of said rear bar l2 has straight portion 66 which flaresawayfrom the adjacent ends of said frontbar ill.

Cooperating with each end of said rear bar i2, and pivoted by its innerend thereto by means of rivet !'l,-is plate l8, conforming to thecontour of said rear b'ar l2 and overlying its inner face, with theexception of bend l9, made adjacent 15 elevation i5 and innertermination of flaring end portion iii of said rear bar 52. Said bendH3, in the operative position of plate l8 contacts and bears againstsaid enlargements l l of front bar l9.

Passing through said bend i9 is pin 28, the

g0 outer end of which is doubled up as at 2! for frictionally engagingthe adjacent free end of plate is, the pin being longitudinally disposedwith respect to the plate.

The .inner sharp point of pin'zii extends within 5 the space defined by,and intermediately of bulge l4 and the adjacent body portion of frontbar l5, as is clearly seen in Fig. 2. As shown, the sharppoint of 2B ofpin extends inwardly, away from the free end of plate l8.

39 Made longitudinally and centrally of bar l2, and coextensively withelevations I5 is recess 22 within which portion of pin 28, which isbelow plate i8, is adapted to spring into and be locked thereby to barl2 when plate l3 and pin 20 are in an operative position therewith, asis seen in Figs. 1 and 5.

To use the fastener hereinabove described with a collar, each wingthereof is inserted between bend l9 and enlargement ii, at each end ofthe fastener, the vertical hem portion of each wing being shifted untilthe same is well past the sharp point 29' of pin '26. Each wing willthen be engaged by pin 20 and thereby both ends of the collar will beheld in a rigid engagement by the fastener so that no lateral pull uponthe collar will be able to disengage the same from the fastener. In theoperative position of the fastener with the collar, the front bar I!)will remain forwardly thereof, with its ends and enlargements l loverlying the wings, while bar l2 and plate i8 will remain rearwardly ofthe collar wings,

thereby clamping the collar wings therebetween.

To disengage the fastener from the collar the 5 wings thereof areslightly pulled towards the center of the fastener, until pins 28 aredisengaged therefrom. Thereupon the free ends of plates I8 are manuallyshifted to spring pins 20 out of recesses 22, the position illustratedin dotted lines in Fig. 1, and said plates I8 are angularly swung as faras they will go. This operation will remove the sharp points of pins 20out of the path of the collar wings and thereupon the fastener isremoved therefrom.

From the hereinabove description it will be apparent that the fastenerherein disclosed provides a simple means of holding collar wings inposition, with means therein provided for'positively engaging the collarWings and preventing the fastener to slip out of engagement with thecollar wings until manually released from the collar wings. It will alsobe apparent that the ends of bars degree of tension; in fact there maybe a small gap therebetween thereby eliminating strong frictionalcontact with the collar wings, and thereby minimizing the wear and tearthereon.

While there is described herein a preferred embodiment of the presentinvention, it is nevertheless to be understood that minor changes may bemade therein without departing from the spirit and scope of theinvention as claimed.

.What I claim as new is:

1. A fastener for fastening fabric material comprising a pair of bars inrigid mutual engagement intermediate their ends, the free ends of saidbars being in a resiliently yielding mutual relation for clamping fabricmaterial therebetween, a plate pivotally connected on one of said arsfor angular movement toward and away from said bars, and a pin carriedby said plate, the sharp point of said pin being disposed away from theends of said bars for positively engaging the fabric material when thesame is inserted within said bars.

2. A fastener for fastening fabric material comprising a pair of'bars inrigid mutual engagement intermediate their ends, the free ends of saidbars being in a resiliently mutual relation for clamping fabric materialtherebetween, a plate in pivotal engagement with one of said bars, saidplate being provided with a bend, and a pin extending through said bend,said pin being in rigid engagement with said plate and in a longitudinalrelation therewith, said one bar being provided with a longitudinalrecess wherein a portion of said pin is adapted to spring into forlocking said pin and said plate with said one bar when said plateremains in an operative position relative to said bars, the sharp pointof said pin being disposed away from the free ends I!) and I2 need notbe under a great of said bars for positively engaging the fabricmaterial when the same is inserted between said bars, said plate beingadapted for angular shifting movement with respect to said bars forspringing said pin out of said recess for disengaging the same from itsengagement with fabric material.

3. A collar wing fastener comprising a pair of bars, said bars beingconnected intermediately of their ends, the two ends of said bars beingadapted to receive therebetween a pair of collar wings, a plateinterposed between said bars at each end thereof, said plates beingpivotedly connected at one of their ends on one of said bars, a pinrigidly carried by each plate, the sharp points of said ly toward saidpivotal connection of said bar with ment of said plates with relation tosaid bars.

4. A collar wing fastener comprising a pair of bars, said bars beingconnected intermediately of their ends, the two ends of said bars beingadapted to receive therebetween a pair of collar wings, a plateinterposed between said bars at each end thereof, said plates beingpivotedly connected at one of their ends on one of said bars, a pinrigidly carried by each plate, the sharp points of said pins beingdirected inwardly toward said pivotal connection of said bar with saidplates for simultaneously engaging a pair of collar wings, and meansrigidly engaging said pins with one of said bars, said means comprisinga recess formed in one of said bars, said recess being adapted to engagesaid pins intermediate their end portions when said pins are in theiroperative positions, said pins being rendered inoperative when said pinsare withdrawn from said recesses and pivoted on said bar.
